is she loves me?

she talks a lot with me . goes to restaurant and movie. we used to work in the same office but now I works for another company. still we met 3 to 4 times every weak.one year ago I give her a love letter. but when I asked her about the letter she told me, it is not important to read the letter. but I want to know whether she is interested in me or not

well, time will tell

Simple just ask her directly it will save both's time and it will give an end to day dreaming and you can concentrate on u r work more ... :)
